Professor Irene Manton FRS, P-PLS, FRMS, BA, PhD, ScD. Hon. DSc.

Attended Girton College, Cambridge in 1923, which she left as it was unwelcoming to women. Moved on to study at Gustaf Otto Rosenberg in Stockholm. Became a lecturer at teh University of Manchester in 1928. Received her PhD in 1930, with her thesis on Cruciferae.

Manton spent most of her career at the University of Leeds, where she was a Professor of Botany from 1946 until she became Professor Emeritus in 1969. Her work focused on ferns and algae, specifically hybridisation, polyploidy, and apomixis. She also examined chromosomes and evolution.

Irene wrote more that 170 scientific papers, one book (Problems of cytology and evolution in pteridophyta, 1950) and many general articles.

She taught Professor Mary Gibby as an undergraduate at the University of Leeds.

As a woman she set several records including being the first female professor and first female head of a department at Leeds University. She was the first (and so far only) woman president of The Linnean Society of London (1973-1976). Also she and her sister Sidnie are the only sisters as of 2004 to be elected Fellows of the Royal Society.

In 1990, The Linnean Society established the Irene Manton Prize. It was created for best doctoral thesis in botany.

From the Linnean Society:
"Irene was a ‘woman of her time’. Her life (1904–1988) spanned the better part of the
twentieth century. This period was momentous for many reasons. Firstly, there was a major
change in the role of women within the professions in general, and science in particular.
Secondly, with the advent of electron microscopy, a completely new subject was born and
Irene was present at its birth. Thirdly, science was in the process of changing from being a
discipline pursued by individuals to becoming an industry. Irene was one of a select group
of women pioneers who made their way in what had hitherto been a man’s world.

In compiling this biography, I have not changed my opinion that Irene Manton was an
exceptional woman but I have been surprised at the breadth of her intellect and the depth of
her humanity. No period of her life is without interest and I hope that the story that follows
will give insights into her as a person, into the work that she carried out, and into how and
why she managed to make the transition from being a ‘classical’ fern cytologist to being a
world leader in a new and technically-sophisticated branch of biology."
